We need to hide SMRAM from guests not running in SMM. Therefore, all uses of kvm_read_guest* and kvm_write_guest* must be changed to use different address spaces, depending on whether the VCPU is in system management mode. We need to introduce a new family of functions for this purpose. For now, the VCPU-based functions have the same behavior as the existing per-VM ones, they just accept a different type for the first argument. Later however they will be changed to use one of many "struct kvm_memslots" stored in struct kvm, through an architecture hook. VM-based functions will unconditionally use the first memslots pointer. Whenever possible, this patch introduces slot-based functions with an __ prefix, with two wrappers for generic and vcpu-based actions. The exceptions are kvm_read_guest and kvm_write_guest, which are copied into the new functions kvm_vcpu_read_guest and kvm_vcpu_write_guest.
